[Hydrocellular dressings, 25 years of evolution].

Manufacturers have worked to increase their absorbency, to make them easier for caregivers to use and to improve their comfort for the patients. This class now comprises a diverse range of dressings. Their inclusion on the list of products and services approved for reimbursement, given the low level of evidence provided by the clinical studies currently available, depends on their technical characteristics assessed in vitro.
